Answer:
y is the dependent variable
Step-by-step explanation:
Firstly, in a linear equation, we have the dependent and the independent variables. The dependent variable is the one whose values are obtained from the independent variable. The independent variable is the variable which we already know its values.
Hence, we say that the independent variable is the variable in which the dependent variable is based.
Now, back to the question, our equation says y = 2x. To get the values of y, we cannot do this without having a prior knowledge of what the values of x are. Hence, we can say that y is a variable which values are dependent on the values of x. We can thus call y the dependent variable and x the independent variable in this question
